πŸ”₯ CALLING ON @Hacker0x01 ! - A SILENT FIX CASE. Jan 21: Reported a HIGH sev bug to program, triaged by/via H1. Jan 26: Program confirms it's "legitimate bug, warrants fixing", then marks it Informative for irrelevant reasons. My technical rebuttal: ignored. Jan 30: Requested H1 mediation. 5 months of silence. This week: SILENT FIX. found my exact prescribed fix silently merged April 16. No bounty, no credit, no mediation, no reply. @Hacker0x01 its been a whole 5 months since I requested mediation on report #3519919. Not even a beep. Instead of getting mediation, I got silent fix. Anyone home? #bugbounty #web3security

Obfuscation =/= Encryption πŸ” Remember: if we found it, reverse-engineered it, who knows who else had done same without responsible disclosure? Just... fix it, ASAP. Our job is done here. Value added.

My other concern is that we have stopped creating content. We are only consuming what AI and search engines present. When last did we make a forumnpost? A post on Quora? A medium original article? A real solution posted on StarkOverflow? We are now recycling and doing. Fine, but in the next 5 years, guess what happens? We must not forget the art of publishing. Writing. Authorship. Its a way of protecting the future. Even in security research. 0daysec.xyz

A crit, reported in just 2 paragraphs, triaged within 2 hours and 10k awarded within 3 hours. That's the epitome of a true hacker and zero-day hunter-killer. You're welcome!

Our recent works @Zer0day_sec keep re-hammering a cold fact, the reality of which many projects are still trying to grapple with: THE DAYS OF SECURITY BY OBSCURITY ARE OVER! If we found it, malicious actors can find it, and could have already found it too. A dangerous thing about these "secrets" is that their exposure/impacts could be STEALTHY!! So, dear projects, even while you're still arguing bounty, JUST F*CKIN FIX IT ALREADY! @Hacker0x01 @immunefi @HackenProof

Or are you trying not to fix so that you won't be bound to pay a bounty? That doesn't make sense. Does it? And as whitehat, we are bound by strict program rules. When we find these, there is a strict limit to what we could do with them. We dont want to break these rules.

If you see very dangerous gambles many high-profile projects are taking, you'd be amazed. Thats why some exploits, info leakage, data exfils, how ever sophisticated they look from they outside, would never surprise me. They are trivial. A case study: One could get hacked anytime using a hardcoded secret that looked benign on the surface, the secret was just used for nothing meaningful. And in their program details, they shot themselves in the foot by classifying such weaknesses as OOS. What they obscured, or o they thought, was the fact that same data combined with some other data were called at runtime for critical cryptographic calls. We saw this, yet, they claim its OOS. Tracing that call required either advanced tooling or insider info. As we speak, secret is still live. Not rotated. This is disappointing.

You should be grateful we found it first.l, or at least showed you it could be found. But wait, were we really the first to find it? Only time will tell, if you ever declared all your exploits. FIX IT.
